Aws-sdk-js: apigateway.putIntegration type for AWS Lambda

[brianleroux]

It appears that API Gateway does not currently allow to associate an Lambda to a an method request integration. (But maybe I'm just missing how to do it in the docs!)

[chrisradek]

@brianleroux
You would want to include the Lambda function as part of the uri.
The uri is probably the trickiest parameter to specify the first time around. There's clearer documentation on how to build the uri on the API Gateway docs here:
http://docs.aws.amazon.com/apigateway/api-reference/resource/integration/#uri

So, if you wanted to call a lambda function, the uri would look something like this:
arn:aws.apigateway:{region}:lambda:path/2015-03-31/functions/{lambda function arn}

See #769 for more discussion on the topic.

[brianleroux]

awesome thx. (had figured this out after looking at swagger gen … docs could use some colour!)

[brianleroux]

hmmm. still having troubles.

{ httpMethod: 'POST',
  resourceId: '6pfvuf',
  restApiId: 'afz6ejjune',
  uri: 'arn:aws.apigateway:us-east-1:lambda:path/2015-03-31/functions/arn:aws:lambda:us-east-1:455488262213:function:begin-account-api-invite',
  type: 'AWS',
  integrationHttpMethod: 'POST',
  credentials: 'smallwins-api-lambda' }

With the error:

{ [BadRequestException: Invalid ARN specified in the request]

But it looks good to me?

[chrisradek]

@brianleroux
I had a typo in my example, there should be a colon after the first aws in the arn, not a period. Please give that a try!

[brianleroux]

jeez, I didn't even see that period. (must be getting late!) unfortunately still getting an error. these params:

{ httpMethod: 'POST',
  resourceId: 'dl5emh',
  restApiId: 'lko08s3rjb',
  uri: 'arn:aws:apigateway:us-east-1:lambda:path/2015-03-31/functions/arn:aws:lambda:us-east-1:455488262213:function:begin-account-api-register',
  type: 'AWS',
  integrationHttpMethod: 'POST',
  credentials: 'smallwins-api-lambda' }

get this:

[BadRequestException: Invalid ARN specified in the request]

:grimacing:

[chrisradek]

@brianleroux
I suspect your credentials also need to be the full arn. I'll verify on my end if that's the case.

[chrisradek]

@brianleroux
I ran a test on my end, and an ARN should be provided for credentials as well.
Let me know if you still see errors after changing that!

[brianleroux]

Awesome! that (sort of) worked!

Wed Jan 13 23:26:16 UTC 2016 : Execution failed due to configuration error: API Gateway does not have permission to assume the provided role

guessing this means the thing in my credentials needs but struggling though that config (alas)

Kind of crazy. Appreciate your help!

[chrisradek]

@brianleroux
Are you seeing that message as a result of running putIntegration, or from actually testing the method?

[brianleroux]

result of actually testing (after editing the role tho / the putIntegration
works now w/ the role arn specified)

[brianleroux]

For reference this is what I'm using in the putIntegration call:

{ type: 'AWS',
  httpMethod: 'POST',
  uri: 'arn:aws:apigateway:us-east-1:lambda:path/2015-03-31/functions/arn:aws:lambda:us-east-1:455488262213:function:begin-account-api-invite',
  credentials: 'arn:aws:iam::455488262213:role/smallwins-api-lambda'}

(again huge thx for your help in getting this working)

@brianleroux
I'm going to close this issue since the original question is solved, and your errors appear to be related to policies and apigateway.
Feel free to comment or reopen if you're still having issues with putIntegration.

I'll be back…!

[loloDawit]

I'm getting Invalid ARN specified in the request error. I'm following the API Gateway example. Not sure the source of the error. see attached screenshot.
